THE-NATIONAL CASH REGISTER ooivrranv; or narrow, OHIO, A conronarron or OHIO, ,(mconron'arnn IN 1906.)

Be it knownthat I, FnANc s G OSBOR N, citizen'of the United States, residing at Detroit, county ofW'ayne, State of Michigan;

have invented a cert-ainnew and useful Improvement in Gash-Registers, and declare the following to be a full, clear, and exact description of the same, such as will enable .others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to cash registers,-

and has for its object improvements in that class of registers in -which a printed tabletis brought to a position to be seen by the customer, so that the customer may be able to know that the person operating the register has properly actuated it.

In carrying my invention into effect, I employ a Series of vertically movable tablet rods a corresponding set of keys, key levers or primary actuators, which control the movement of the tablet rods to an intermediate position; that is, a movement toward but not into full indicating position;

a secondary actuator which moves the shifted tablet rods to full indicating or exposed po'sitionyand a register actuated by devices carried by the key levers, which devices drive'the register during a stroke in one direction and become operatively disengaged during the stroke in the opposite direction, said'devices being arranged and constructed so that the engagement of the register and an actuating device during the positive or actuating stroke will prevent the overthrow of the register- The secondary actuator which I employ 3 5 common to all the tablet rods so thatwhen two or more tablet-rods are moved tog-the intermediate position, the secondaryactuator will move them simultaneously tothe exposed or indicating position.

In the register to which these impr0ve-- ments are applied I use several sections or" banks, of keys; thus the keys pertaining to the tablets which indicate cents'are in'one section, thekeys pertaining to 'th'e. tablets used to indicate dimes or fractional'p arts of a dollar are in another sectionfandthe keys pertaining to the tablets used to indicate dollars are in a third section. One key in each section may be in a position with.-

its inner end raisei at the same timethat a aspec ification of Letters Patent. Pmt t d A 3% 1 I "Application filed May 18, 1892. Serial lilo. 433,483. r i

key in another section isoperated to raisea tablet, but two'keys cannot be operated in the same" section simultaneously5'the main object of this is to render it unnecessary to I employ in the recording part ofthe machine a total adding mechanlsm .in which the wheels will carry from. one to another while p in simultaneous operation.

In the drawings, Figure 1 is a sectional View from front to rear showing one key and the parts operated by it. Fig. 2 is a front elevation of the stops that prevent simultaneous movement of more than a single key in the same srntion. Fig. 5?. is a perspective of a pair of the stops of Fig. 2, showing the'position of the front and rear fbanks with respect to each other. Fi 3 shows a form of stops adapted to pro uce equivalent results. Fig. 4 is a detail of the cam guide used to effect proper movement of the tablet rods. Figs. 5 and 6 show the same parts that are shown in Fig. 1 and indicate the position taken by the parts at different times in the movement of-them. Fi 7 is a rear elevation showing particular y the tablet rods and their location above the keys, and Fig. 8 a perspectiveview of the rods and graduated racks actuated thereby.

A represents the case of the machine, B is a key lever fulcrumed on the rod Zr and extending throughthe walls of the case; the

e'nd outside of the case is provided with a finger plate B; the end inside of the case extends under the tablet rods C, and under the stops S S. y i

S represents a stop of which there-are in the machine a number equal to all the keys. Each stop S hangs from a pin 8 that is supported by the case or apart of the frame work; from the same pin 8 depends asecond stop S; thestops are wedge shaped in form and hang from their small end; the large ends occupy the entire space between fixed points, except just sufficient space to permit lever is thrown upward between the stops, the stops and lever fill the entire space be; "tween the fixed points. The fixed points for the passage of one key leverwhen one key the stops S are "the posts or framework P P, shown .in Fig. 2. The fixed points for the stops S arev P, P, P and P posts P P divide the stops S into three sec- The" p tion's, one of which is between the posts I posts I? and P. The stops S of the front- .key lever B has passedi .and'while it is still there P'Pflasecond of which is between the posts P P and a third of which is between the rank differ in shape from the rear stops S;

each'stop S has-a portion cut away from each side, leaving a narrow stem 1 sand forming-anopening between each two ad-' acent stops; the openingio is ,of. a size to permit the end of a key: -ver B to'be re- .10

teem of the the opening 0 e stops S will 'ceived within it, and w swing to one side and permit a second key bars working" in guides formed in two hori, 'zontal pl'atesm and the upper one of "which, a, supports the tablet rods m the normal or inexposed position by means of position the pawl will hold the tablet in shown in F ig '1. c ofeachfpawl stands 1n the wide notch 0 'of its respective tablet rod. When a tablet lever tobe thrown up between them; but the rearmost bank of stops S not vbeing provided with any similar cut away part, av .jsec'ondkey lever in the same section cannot be raised. The combined action of the stops thus prevents the lifting of more thanrone key lever in a section, but allows one key lever iii each section to be lifted immediately succeeding the lifting of a key lever in another section, and while the first liftedv key lever is still in its'elevated position.

The tablet-rods C are preferably straight lugs w on the tablet rods. .Each tablet rod is provided'with two wide notches '0 and c, and a'number'of small teeth 0' between the two wide notches. The tablet rods are raised slightly by means of the primary actuator,

in this case the key lever B,,and' the tablet rods-are held in the intermediate posit on by triangular-shaped pawls. C. These pawl's are pivoted-on the pin or rods, and

for each pawl is provided a spring d which tendsto hold thepawl in the'normal posit on .In this-position the point rod vis raised by its key lever, the lower shoulder formed by the notch 0 strikes the point of its respective paw-l and tilts 1t into the position shown in Fig. 5, so that the point of the pawl will engage theteeth c and in this the intermediate position, the spring d resting upon one of the points of the triangular pawl as 7 shown. It will be seen that the tablet rod between the teeth a? andthe lower wide'notch 0 is provided with a smooth surface the object of which is to permit the tablet rod to drop back so that the teeth a will engage. the-pawl in case the tablet rod is overthrown by the key lever. When the tablet rod is raised by the secondary actuator to expose the tablet, the point of the.

pawl C will be opposite'ithe wide notch c and free 'to resume its normal position as shown in Fig. 6, the tablet being held 'in the exposed position by 'the lifting device of the 'secondary actuator. When the rod'ofgan ex- 'of the pawl when the tablet rod descends 'normal position the'pawl will again be'op- I key levers B.

eaiis posed. tablet becomes disengaged from the lifting device upon a subsequent operation of the machine, the upper shoulder at the lower wide notch a will strike the point and rotate the pawl to the position shown indotted lines in Fig. 6, so that the awl will not interfere with the descent of the tabletv rod. When such tablet rod'is in its link L, crank K, the-ratchet wheel and shaft w. The lifting bar or wing W is rigidly carried-bytheshaft w which is journaled in suitable hearings in the side frames of Y the machine and this shaft is provided with a ratchet wheel with which a pawl Q, engages to permit rotation in one direction only. The shaft is also provided with a the upper end of the link L. The pin. K? also works in two eccentric channels is having-shoulders g and g, as shown in Fig. -l. At the lower end of the link L is a-weight Z carried by two arms pivoted at Z and which weight extends across vthe entire series of The-operation of the primary and secondaryactuators in elevating a tablet rod,

.is as follows: When the parts are at rest,

the tablet rods-all down in their concealed position, the pin K will be at the lowerpart of the cam track 7: resting against the stop when the finger rest B is pressed downward, the inner end of the key bar B is raised,the link L is raised until the pin K traversing half of the. cam slot It strikes against the stop the tablet rod is also par tially raised by the same movement passing up high enough so that the pawl O catches into the teeth 0 and prevents the tablet rod from. dropping again; if now the operp 115 B, the Weight Z becomes operative, the link L drops, the pin K drops out of engageative force beremoved fromthe finger plate ment with the stop g,'and the pinK continues'the circuit of the cam slot k until it strikes against the stop g1; Thefirst move:

ment of the t'abletrod lifted the arm to into the path of the rotating wing W, and

the rotating wing V is so adjusted that 'at the moment the pin K 'engages the stop 9, the wing W is nearing thearm w, asshown in Fig. 3 and as the link L drops, and the crank K. completes its'revolution under the impelling force .of the weighted link'L, the wing W liftsthe tablet rodcompletely. up v The tabletthus moved, to the exposed; pos 3 g.

9o crank K having a slot. in which works the y wrist pin K projecting laterally through inn is held in that position by the engagement of thewing W and the lug w on the tablet rod and will remain in that position until the subsequent depression of a key lever" which causes the wing to rotate as above described, whereupon the wing passes from under the lug wand the tablet rod will as;

scen'd, the downward movement of the tablet rod shifting the pawl C as before explained.

In connection with each tablet rod, is a rack adapted to givemotion to the register wheelfthe rack is on a vertical rod independent of the tablet rod but operated by the same key. At the upper end of the vertically movable rod 1" is a rack. r connected to therod 1" by pins traversing oblique parallel slots in the rack 1'', above the rack r onthe pin M is-an ,arm m, and across the case behind the rods 7 are two rods 4; o; the free end of the arm on engages when the rod 1" is dropped with the rod 11 and the arm is thrown into a position to hold the rack firmly down upon the pins 7' W; the teeth of the rack are also thrown forward to a po sition to engage with and actuate the pinion R intermediate between the rack and the, register wheel B. When the rod 1' islifted in operating the key B, the free end of the arm m engages with the rod 2; and turns the arm to a position to permit the rack r to rise and move backward on the pins r r and drop with the rod r past the pinion It without actuating it in the reverse direction.

' [By looking the rack 4" to the rode", the rack ca not become disengaged from pinion R untilreleased by arm m, and since this release takes place at the end of the upward stroke ofrod r-the're can be no overthrow of the register during the positive stroke of the I keysij This is of the utmost importance,

sincef if means are not employed for positivelylocking the keysto the register during the positive stroke, it will be possible .by suddenly arresting the depression of a key during the positive stroke to effect an overthrow of the register. Any suitable mechanism may be employed to prevent overthrow at the completion of the positive stroke of the key, such, f0r example, as by. engaging the rack r with the casing, as shown, at the end of the positive stroke. This engagement of a rack which operates a register with a stationary stop at the completion of the positive stroke of a key to prevent over throwhas been suggested in, the art. I am not aware, however, that anyone prior to myself has suggested means by which a key can be coupled positively to a register to effect a positive movement thereof without overthrow. of that with such mechanism has been employed a device for preventing overthrow at the completion of the positive stroke.

In, place of th'e triangular shaped S with their cutaway parts forming the opening 0, the form of the stop showh in Fig. 3 may be used in which one set of stops consist of a number of disks Usliding on arod u, and the second set of stops consist of an equal number 'of similar disks U slid ing'ion a rod u; The-key stem B passes between the rods u, a and between the ad acent stops on the rods. The stem of the key B is cutaway at B so that a-fter the stem.

their edges beveled so that the o'peningatv the edges between adjacent stops on the same? bar is much greater than is the space between them nearer the bar, and a second key in the same section cannot be forced between the stops, because in the same section there would only be space for the stops belonging to that section and for one key bar.

connection with the disk steps of Fig. 3, the un-cut-away portion of the key bar en-v gages with the section stops U, and the -cut away portion B engages with the stops U that pass entirely across the case.
